. T0 aZZ whom, it may concern:

Be it known that I, OLE O. KITTLESON, of the town of Lee, county of Lee, and State of Illinois, have invented a new and useful Iinprovement in Barbed-Wire Machines, of which the following is a full and clear description of the parts pertaining to my improvements, reference being had to the accompanying drawings, in which Figure 1 represents a top or plan view of the machine containing my improvements; Fig. 2, a plan view of a short section of the barbed-wire made by my machine; Fig. 3, a

My invention relates to that class of barbed wire machines which make doublestrand 3 5 barbed wire, twisting the two strands of wire together, and at regular intervals placing upon the two strands a single barb, which passes between the two wires of the strand and wind about them.

My invention consists in the particular construction of the coiler-head, which applies the barb to the strand and winds it around the double strand, leaving the ends proj ecting in opposite directions, with the coil of the barb I 5 in the form of a coil, so that the wire coils lie' side by side. I

-It further consists in the special attachments for applying the barb and holding it as it is Fig. 12 is a vertical (No model.) i

being coiled; and, also, in the combination of the attachments to the coiler-head, whereby its movements in connection with the double strand of wire are controlled, all as hereinafter more fully described. I make a frame for holding the operative parts of my invention in any ordinary form of frame of barbed-wire machines, with the ordinary attachments for holding the wire-spools and the reel for reeling up the barbed 'wire.

In the accompanying drawings, A represents the top of the frame.

B is a portion of the frame that carries the spool upon which the barbed wire is wound. This frame B revolves to twist the barbed-wire strands O in the ordinary manner.

D is the main shaft for transmitting power to the various operating parts of the machine.

E is a gearing for revolving the frame B to twist the main strand of wire.

F is a drum, around which the barbed wire passes between the barbing apparatus and the spool upon which it is wound, this being for the purpose of preventing the twist ofthe main strands from passing directlyback to the barbing device. Aratchet-wheel, G, is fixed to the shaft of drum F, and a crank-arm, G, is sup- 7 5 ported loosely thereon. A pawl, G, at the upper end of said crank-arm engages the teeth of ratchet G. The crank-arm and pawl are reciprocated by the pitman, connected at one end with the crank-arm G and at the opposite end with a crank-pin at the end of shaft I, which latter is revolved continuously by the bevelgears H. An intermittent rotation is thus imparted to the ratchet-wheel G- and drum F. I

K is the wire as it passes into the machine, there being two strands passing side by side into the tube L. This tube L lies within the tube or cylinder M, to which the coiler-head N is rigidly attached. The tube or cylinder M 0 has rigidly attached to it the cog-wheel O. The tube L has a weighted arm, Q, the weight serving the purpose to always hold this tube in its normal position, excepting when it is turned, as hereinafter specified, a certain dis- 5 tance regulated by the arm Q, which serves as a stop by striking the frame A. The object of having the tube to turn will be explained below.

R is a segmental cog-wheel, which engages with the wheel 0 to turn the coiler-head N at proper intervals for coiling the barb around the double wire-strand.

S is an arm projecting down from the cogwheel 0 and strikes against the pin T on the segmental cog-wheel B, so as to always insure the starting of the cog-wheel O with the tube ,which carries the coiler-head N at a certain point in the revolution of the segmental wheel R. v

U is a stop or rest just in front of the coilerhead N, against which the end of the barb that is passed between the two wires of the strand is held while the barb is being coiled around the strand.

V is a presser-arm that presses upon the end and holds it in place against the coiler-head N.

I The stop U consists of a plate bolted to the machine-frame and preferably (see Fig. 8) eX- tended into proximity with the tube L, so as to support the barb close to the strand-wires. It is preferably provided with an elevation at n, for a purpose hereinafter indicated. \V hen the coiling of the barb is being accomplished, the presser V is thrown into position to hold the end of the barb, as above described, by the spring 0, secured to the frame A.

a. is acam secured to the shaft D, which cam is for the purpose of raising the presser V out of position after the barb is formed, and thereby freeing the end neXt to the coiler-head, so as to admit the free passage of the barb from that point. The cog-wheel Z) is also secured to the main driving-shaft D, and thereby communicates power through the supplemental gear 6 on the shaft 6 to' the gear-wheel (Z on the same shaft as the segmental gear R, which drives the pinion O 011 the coiling-head shaft M. The coiler-head N is hollow, and is pro vided with a face-plate cut away at the center so as to leave an opening, as shown in Fig. 8, thus forming at the front of the head an in ternal flange for the greater part of the circumference. The twisterhead is also provided with a notch, f, through which the wire 9 is projected, from which the barb is cut, as shown in Fig. 9. The barb-wire 9 passes through an eye in the upright part of plate g, bolted to the frame A, and also through a groove, 9', in the block H, secured to frame A. The groove and eye are inclined to the axis of the coilerhead, so that they deflect the wire and cause it to pass obliquely into said head.

At there is a wide groove to receive the movable and stationary knives or cutters h h. The knife or cutter h is held in its sliding carrier h" in an inclined position, and is ground on the lower end at an angle to the horizontal, as shown in Figs. 15 and 16. The carrier 7&2 is operated by the cam 45 on the shaft I by means of a pivoted bent lever, j. The cam t raises the weighted end k of this bent pivoted lever and throws the knife h forward to cut the barb from the wire 9.

Z represents the ordinary feed-rollers, that are operated by means of the pitman m to feed the wire gforward at the proper time into the coiler N, as above described, the pitman m/be ing operated by the crank-wheel m on the shaft e of the supplemental gear 0.

The operation of my machine is as follows: WVhen the wires which form the strand are put in place through the tube L, which forms a holder to receive and keep apart the strandwires and prevent their twisting, the wire 9 is fed forward, its end passing through the notch f between the wires of the main strand and obliquely through the opening in the faceplate, so that its ends lie on opposite sides of the face-plate, as shown in Figs. 8, 9, and 10, and the knife is thrown forward so as to cut the barb from the wire. The segmental wheel R then engages with the cog-wheel O and commences to revolve the coiler, and one end of the barb is thrown down against the stop U, the presser V immediately coming against it to hold it in place. The other end of the barb is carried around the two wires of the strand, passing inside of the coiler-head, forming a coil, (clearly shown in Figs. 2, 3, and 4,) it being carried around by the notch fin the coilerhead. Just at the time that the end which is carried around the strand is brought up to project in the opposite direction from the end which rests against the stop U, it passes out of the notch f, so as to be carried forward around the drum F, the tube L is revolved by means of the barb striking against the wires of the strand till the stop Q strikes the frame, this qua-rter-revolution bringing the strand-wires from the vertical position shown into a horizontal one, and causing the end of the barb to be wrapped a quarter of a turn more than it otherwise would around the up per strand-wire, so that in the finished article the end of the barb will project in a direction parallel to the plane of the two wires, (see Figs. 2, 3, 4,) instead of at right angles thereto, as it would if the tube L were held in the position shown in Figs. 8, 9, and 10. XVhen the barb is released the weight attached to the arm Q immediately throws this tube L back to its position, so that the wires of the strand are in position as shown in Figs. 8 and 1 2, so that the next barb will pass between the wires as the wire 9 is fed forward to make the next barb, as above described. The raised portion a of the stop it acts as a guide to the strandwires between the coilerhead and the drum F. The mechanism for turning the drum is so timed that it advances the strand-wires just after each barb is applied. The segmental wheel R is brought into operation so as to turn the coiler-head at regular intervals, and the other operating parts, which cut the barb, hold it, and coil it, operating at regular intervals to do their work at the proper relative time.

, It will be seenfrom the above description that I make double-strand wire with a singlewire barb, which passes between two wires of the strand and is wound around both wires, the coils of the barb lying side by side upon the wire-strand.

Having thus fully described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The notched coiler-head provided with a face-plate, forming a continuous internal flange around the greater part of the head, and having an aperture in said face-plate, in communication with the notch, said construction permitting the barb to be inserted throughthe notch and across the flange, and after coiling to be carried wholly to the front of l the plate, substantially as described.

2. The combination, with the notched coilerhead having a faceplate provided with an aperture communicating with the notch, and constituting a continuous internal flange around the head except at said aperture, of automatic barb-inserting mechanism constructed and arranged to insert the barbs in said head partly behind and partly in front of aforesaid flange, substantially as described.

3. The combination of the strandwire hold er, provided with openings for the passage of the strand-wires and adapted to prevent their twisting together, the notched coiler-head having the internal flange cut away adjacent to the notch, but otherwise extending continuously around the head, and the automaticbarbinserting mechanism constructed and arranged to thrust the barbs between the strand-wires and into the coiler-head partly behind and partlyin front of said flange, substantially as described. a

4. In combination with the eoilef-head and the-strand-wire holder. provided with openings for the passage of the strand-wires, and

adapted to hold them apart and prevent twisting, the automatic barb-inserting mechanism, and the stop, relatively disposed as explained, for catching the end of the barb thrust between said strand-wires and holding it stationary during the coiling operation, substantially as described;

5. A holder for the strand-wires, capable of turning, in combination with a twister-head, a stop to catch one end of the barbs, stops to limit the rotary movement of the twister-head,

and a device-such as a weightfor restoring the twister-head, after displacement, to its normal position, substantially as described.

6. The hollow tube L, the twister-head N, segmental cog-wheel R, cog-wheel 0, stop Q, and weighted arm Q, or their equivalents, for holding the wires of the strand to receive the barb between them and then admit of their being \Vitnesses:
